This mod replaces all boss battle songs with songs from the very popular video game "Shovel Knight."
These songs are:
Basic Boss Fight = The Vital Vitriol (Plague Knight Battle)
Mom Fight = The Destroyer (Tinker Tank Battle)
Womb Fight = The Rival (Black Knight - First Battle)
Satan Fight = The Spin Controller (Propeller Knight Battle)
Isaac Fight = The Bounty Hunter (Treasure Knight Battle)
Chest Fight = The Betrayer (Enchantress Final Form)
Dark Room Fight = The Claws of Fate (Mole Knight Battle)

If you feel like the music doesn't fit with the boss fight, let me know and I'll change it!
